Abstract

A sheet feeding and separating apparatus includes a multiple piece entrance guide located between a stack from which sheets are to be fed and a retard nip. The guide includes a polycarbonate base member and a high friction urethane retard member. The urethane is ground on the leading edge to an exact angle to promote shingling of sheets and the breaking up of slugs prior to entering the retard nip.
